Main • Rex, the protagonist – a timid, irritable runt. He is quick-witted and usually comes up with plans to get out of the scrapes the gang finds themselves in. However, he can also annoy the others by being a smart aleck. His favourite superhero is Rocket Raymond. He is the leader of the gang, even having his name, Rex, translating to "King" in Latin. • Bad Bob is a "big, fat slob", interested in food and TV. His friends, and occasionally even he himself, describe him as a "Big, fat, jelly-wobbly, fat bastard", usually getting cut off towards the end. He is distinguishable by his eye patch, which changes from eye to eye, and often carries around a
revolver almost the size of himself. However grumpy he might be, he is intelligent and loyal. Bad Bob is also known to build unique gadgets and inventions out of knick-knacks and everyday household objects, such as using an empty can of beans as a form of time machine. • Wendy is the only female housemate, distinguishable by her eyelashes, pink colour, noticeably hemispheric breasts, and wears a red (or starting with series 2, pink) bow on her head. She is cynical, sarcastic, and fiercely independent. Wendy provides solutions to problems albeit in a distant or non-caring way. She speaks in a Mancunian accent. • Vince is the pet of the household, although all four are dogs. He is distinguished by his prominent buckteeth and mismatched eyes. He speaks in single words or short disjointed phrases, his favourites being "Spaghetti", "Tuesday", "Jam", and "Trousers". Vince suffers from "Random
Pavarotti Disease", causing him to randomly blurt out snatches of opera. While he appears to be unintelligent, he occasionally shows great ingenuity, for example by building an elaborate
Heath Robinson machine designed to kill a mouse. The other members of the gang often respond to Vince's random outbursts by irritably telling him to "shut it". Vince often has a habit of copying what others have said, sometimes even if they have just said it in their minds, which Bad Bob finds really annoying.
Others Many one-off and recurring characters in Rex The Runt are voiced by various well-known UK celebrities. These include: • Doctor Dogg is a medical doctor. Moustachioed, complacent and greedy, he's an opportunistic money-grabber, whose habitual charge for any treatment is "ten
quid" – regardless of whether the cure works or does more harm than good. He isn't above using the main characters in
medical research. Voiced by
Paul Merton. • Arthur Dustcart, another semi-regular character, who first makes an appearance in the last episode of the first series, but appears quite frequently in the second. He is an ugly but experienced
dustman, sporting sleepy mismatched eyes, a
neckerchief, a pair of dirty
underpants and a large nose with prominent
nasal hair. Despite his grotesque appearance and smell, he and Wendy get on rather well, much to the annoyance of Rex. He becomes a friend of the household when he helps find Rex after he was turned into spaghetti. Voiced by
Arthur Smith. • Mrs. Bloomers, head of Kumfy Kennels. Treats dogs with care, until she put Vince in the kennel and he ate a chihuahua. Voiced by
